Interesting. looks a promising way to mimic double click handler.

But I see in the utils, you cached the date in a shared variable for all tree items, which might cause problem.
E.g. If you quickly click two items in 500ms (interval you set), it's wrongly treated as double click.

you're right, in this way we should find a way to record the tree item as well.

a treeItem has a unique id. consider use that?

yes, but that's something like internal identifier and if we didn't specify it before, we will get undefined when accessing that id. Why not directly assert equal of two tree items? Actually, they are the same object if we just click an item twice.

[Eskibear]

it's fine.

would better to clear the state if a double click is detected. Otherwise, triple click is regarded as two double clicks.
